Sweeden’s Princess Madeleine is to marry New York financier Chris O’Neill. The couple, who met when she moved to the city just over two years ago, announced their engagement yesterday. O’Neill, a 38-year-old partner at New York hedge fund Noster Capital, proposed to the 30-year-old princess earlier this month after asking her father, King Carl XVI Gustaf, for her hand in marriage. Princess Madeleine is the youngest of King Carl and Queen Silvia’s three children and is fourth in line to the Swedish throne. In a video clip posted on the royal Web site yesterday, Madeleine said, “Chris proposed to me in New York at the start of October, and we are very happy.” She described the proposal as “very romantic and intimate.” Sources tell us O’Neill popped the question over dinner at an Upper East Side restaurant, and the couple celebrated with a bottle of 1978 Cristal Champagne. O’Neill said on the video, “Madeleine and I have known each other for two years, and I recently summoned up the courage to ask her to marry me. Thankfully she said yes.” It is believed O’Neill asked the king for her hand after he and Madeleine were spotted dining together with her father and mother at Indochine in late September. A week later, the stunning princess — without an engagement ring — and her parents were spotted at the Green Summit & Royal Gala Award Dinner at the Mandarin Oriental Hotel. The couple, who have not announced wedding details, say they plan to continue living in New York.
